Proof Server

Proof server releases are now part of Ledger

Starting with Ledger 7.0.0, proof server releases appear on the Ledger page, not on this page. Images for 7.0.0 and later are on Docker Hub as midnightntwrk/proof-server. For the version to run on each network, see the compatibility matrix.

The releases on this page predate that change. Their images, up to 4.0.0, are in the older midnightnetwork/proof-server repository.

Proof Server is a component of the Midnight infrastructure that enables zero-knowledge proof generation, transaction verification, and privacy-preserving transaction processing.

Summary

  • Integrated with the new storage model, making required objects Storable to allow storing MPT leafs as Sps.
  • Added segment IDs to Zswap constructors. These should be set to 1 for fallible offers, and 0 for guaranteed offers.
  • Renamed ZswapLocalStateNoKeys to ZswapLocalState, removing the existing (with keys) state.
  • Switch from Pluto-Eris to BLS12-381.
  • Switched to using data providers instead of direct prover keys and parameters.
  • Add a data provider to fetch key material for Midnight. The source of this may be overridden with the MIDNIGHT_PARAM_SOURCE environment variable.
